Specification of Letters Patent.

Patented Feb. 19, 1907.

Application filed August 30, 1906. Serial No. 332,632.

To all whom it may concern! Be it known that I, RICHARD G. LATTING, Jr., a resident of Chickasha, Indian Territory, have invented certain new and useful Improvements in Machines for Treating Cotton- Seed Hulls; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same.

This invention relates to machines for disintegrating materials such as cotton-seed hulls or the like and separating their components, and has for its object to increase the efliciency and capacity of such machines and to decrease relatively their cost of construction and operation.

The invention consists in the construction hereinafter described and pointed out.

In the accompanying drawings, which illustrate the invention and form a part of the specification, Figure 1 is a longitudinal sect1on of the machine. Figs. 2 to 7 are en larged transverse sections on lines 2, 3, 4, 5, 6, and 7, respectively. Fig. 5 is an enlarged partial section of the cylinder, showing an opening in its lower side covered with reticulated material. Fig. 8 is a partial longitudinal section of a modification, and Fig. 9 is an enlarged cross-section of one piece of ribbed lining.

Numeral l denotesa base, and2 a plurality of posts or standards in which are provided pearings for a shaft 3, having driving-pul- 5 denotes a housing supported on the base and surrounding the shaft.

6 indicates an inlet to the interior of the housing for material to be treated, and 7 an air-inlet provided with an adjustable cover 8.

9 indicates a housing of the same general character as that denoted by 5. It has a discharge-opening 10 for air and the lighter portions of the disintegrated materials. 11 denotes a conduit by which said opening communic)ates with an exhaust-fan, (indicated at 12.

Secured between the housings -5 and 9 and communicating with their interior and their 0 enings is a cylinder, preferably made in a p urality of sections, four sections being illustrated in the present instance. Each section by reference comprises an outer cylindrical shel 12*, of galvanized iron, and a of reticulated material, such as wire-cloth 13. The outer ends of the sections are fitted to and supported upon a ledge 14 of the proximate housing. The other section ends are fixed to similar ledges 15 on the interior of cylinder-supporting ring-standards 16, fixed to the base by suitable feet.

17 denotes rubbing blades or beaters extending from the shaft to the cylinder for disintegrating, mainly by friction, material passed into the cylinder. These are fixed to the shaft by means of nuts 18, drawing the shoulders 19 against said shaft. struction provides that, if desired, the beater may be adjusted, so that the face will be situated in a plane cutting the shaft obliquely. Heretofore in machines of the same general character such beaters of the particular character shown have been arranged on diametrically opposite sides of the shaft, little or no conveying action being thus secured. The

The conbeaters herein illustrated are spirally dis-.,

posed about the shaft and extend to near the cylinder and are in such numbers and such relation that they act as conveyers for the beaten material, their numbers and arrangement being variable, as will be described.

The metal cylinder-sections 12 are provided on their lower part with dischargeopenings 20, which'together extend approximately the whole length of the sections. These are covered by the perforated lining 13, which may be supported between the openings by narrow parts 22 of the outer cylindricalwall. This lining may cover the entire inner surface of the cylinder, as indicated in Fig. 1 by the cross-lines ateaoh end and b the broken lines lengthwise the cylinder-wall between said cross-lines, all being marked 13, said cross-lines showing the lining partially and the broken lines indicating its length.

In operation material such as cotton-seed hulls is supplied by any usual or known means to the feed-opening 6 and air admitted to the inlet 7. Thereupon the air and portions of the hulls are drawn through the cylinderand among and past the beaters, which latter being rapidly rotatedbreak up the hulls and also convey or push along the material being beaten toward the discharge. The heavier portions of the disintegrated hullsare by centrifugal action thrown toward the cylinder and are carried by this action and by gravity to the openings 20 and therrubhing-heaters.

delivered from the machine to be collected l-lining, The'friction of the lining and the and-caredfor'in any desired manner; Such heav er material as is not beaten out and thus- 1 separated in the first section, receives similar treatment in succeeding sections, except that by preference the heaters are not arranged 1nthe last section to convey the material, the exhaust action-being ,sufl icient to remove the lighter material, which at this part of the cylinder has been practically separated from the heavier, which latter escapes through openings 20'. 1

Tovar-y-the actionof the heaters in the sev-v eralsections, theinspiral arrangement is varied-kin the present instance the section nearest the inlet end of the. cylinder. Eight,

heaters make a complete circuit of the shaft,

the next section six heaters, in the thirdfour beaters, and in the last there is no spiral arrangement.- The sections each contain twelve beate'rs- The precise numbers are not material. The conveying action of-the heaters is not essential inthelast section, and -itmayhe-omitted-to avoid crowding the escaping material against the'shoulder 21,-

that surrounds the contracted discharge-cyh inder outlet 22-.-- The: effect of this compara tive'lvsmall outlet and this shoulder is to: concentrate about the shaft the exhaust-cur-- rentvand leave adjacent the cylinder-wall a zone relatively unaffctedbythe exhaust to facilitate the centrifugal and gravitating ac tionhefo re referred to.

The air-inlet 7 in housing 5 has an adjustable'cover 8. 23 denotes a set-screw for fixing-it after adjustment.- I The situation of the air inlet hackof or behind andclosely' adjacenttheopening for charging-material into the cylinder promotes the feeding of. such material by exhausting from the opposite endof the'cylinder in a loose and agitatedstate,- whereby it is evenly exposed to the ace tion of the heaters. r 7 is a second opening and 8 its cover.

Neither is the invention-limited to any particular. form. or 1 kind of cylinderlining material, provided that a part that: covers the lower outlets or outlet is perfo-nrated in manner 'to-permitcthe. escape of-ax' bran.
